Subcutaneous OK: While IM is the standard route, it is also effective when given subcutaneously and is less uncomfortable so it should be fine to give sq. After a few months you can check your serum levels of B12 and you should find that this route is providing adequate therapy.

Vitamin B: Agree with Dr. Baker. Vitamin B12 can be absorbed from both intramuscular & subcutaneous sites. REF: https://pdf.hres.ca/dpd_pm/00026115.PDF
